Rotary depository construction

ABSTRACT

A manually operable bank depository which has a two-compartment rotor with 180* movement for each operation for handling bags or receiving envelopes. The rotor compartments are alternately exposed at a main housing opening closed by a sliding door movable in one direction for exposing first a portion and then all of the main housing opening to receive envelopes or bags. There are cam release and control mechanisms and interlocks interacting between the rotor, drive mechanism and door connecting the rotor with the door for imparting movement to the rotor initiated by door movement. The controls prevent reopening of the sliding door until fully closed after closing movement of the door covers the main opening. The sliding door is angularly located for easy operation and for minimum wall thickness requirements for installing the depository.

SHEET 90F 9 RM a3 7" 2e INVENTOR PAUL A. LEIPELT 5.5" J-I= ATTORNEYS 2- a/tw8ew ROTARY DEPOSITORY CONSTRUCTION BACKGROUND OF THE INVENTION l. Field of the Invention The invention relates to depository mechanisms used by banks and similar institutions to enable customers to deposit for safekeeping, usually after banking hours or at locations remote from a bank, money, papers or other items of value. More particularly, the invention relates to an improved rotary depository construction which will accept deposits of material either in envelopes or in bags, and to a mechanism which may be hand operated easily and has a simple and relatively inexpensive design and construction.

2. Description of the Prior Art Many depository constructions have been used, designed primarily for accepting material to be deposited at a bank after banking hours, for example as shown in US. Pat. Nos. 3,028,074, 3,059,839, 3,114,499 and 3,615,050. Prior constructions have involved either rotary or linearly movable mechanisms, and have been capable of accepting bags or envelopes or both. Some prior constructions have been manually actuated and others have been power driven. Some of the manually operated rotary depository mechanisms have involved two-way rotation of the rotor, first in one direction after accepting a deposit to discharge the deposit into a chute, and then in the reverse direction while closing the depository door and returning the rotor to a position for accepting a subsequent deposit.

Some prior constructions have been provided with one door covering an envelope slot and another door, released by a key lock, for covering a larger slot for acceptance of a bagged deposit. Most manually actuated depository mechanisms have required considerable force to move the rotor or conveyor mechanism of the unit. Ordinarily such manual actuation of the rotor or conveyor is accomplished by connecting one or more of the depository doors to the rotor, and rotor movement is imparted by the opening and closing move ments of the door.

These characteristics of prior manually operated mechanisms have resulted in most instances in requiring power or motorized operation, which in turn has increased the cost amd complexity of the device.

Thus a need has existed in the art for a simplified, in-

expensive rotary depository construction which will accept either envelopes or bags, which avoids the necessity or requirement of power operation, and which is easy to operate manually.

SUMMARY OF THE lNVENTlON Objectives of the invention include providing a rotary depository construction which will accept both envelopes and bags; providing a rotary depository construction requiring little force or effort on the part of the user to impart operating movement to the rotor from movement of the door to expose either an envelope reupon full opening movement of the door; providing a rotary depository construction having a rotor with two similar compartments spaced apart which presents first one and then the other compartment to the main housing opening for accepting deposited material; providing a rotary depository construction in which door movement toward open position, either for exposing an envelope opening or a larger bag opening, when once reversed in direction to close either of the openings cannot again be changed during rotor movement to movement toward open position without first returning the door to completely closed position; providing a door controlled rotary depository construction of the type described which transmits rotary movement to the rotor for 180 rotor motion, commencing just after the envelope opening or the bag receiving opening has been completely covered by the door; providing a rotary depository construction which has a slidably mounted door movable along an upward rearwardly extending plane to uncover the deposit receiving openings, in which the angled extent of the door and its movement enables reduced wall thickness to be used for mounting the depository in the wall of a building served by the depository; and providing a rotary depository construction eliminating difficulties encountered in the art, eliminating costly manufacturing, assembly and maintenance problems, and characterized by simplicity in construction and operation and which satisfies needs existing in the art.

These objectives and advantages are obtained by the rotary depository construction, the general nature of which may be stated as including housing means installed in a building wall forming :a rotor compartment having a main access opening and a discharge opening connected with a discharge chute extending within the building wall and adapted to communicate with a receiving chest; a two-compartment rotor journaled in the housing controlled for one direction movement in indexed 180 increments to expose first one and then the other compartment to the main housing access opening; a rectangular plate-like door, means slidably mounting the door for linear sliding movement in a plane extending upwardly inwardly of theouter building wall surface, the door covering themain housing opening in the closed position of the door, uncovering a slot-like portion of the main opening at an intermediate position of the door, and fully exposing the main housing opening at the fully opened position of the door; the door being movable in one direction from closed, to intermediate, to fully open position, and movable in the other direction from open or intermediate position to closed position; rack and pinion and indexing clutch drive means connecting the door and rotor for rotating the rotor, druring predetermined movements of the door, through 180 during each cycle of door movement from closed to open and back to closed position; means limiting rotor movement to rotation in one direction only; cam and latch control mechanism for sliding door and rotor drive, interacting to prevent opening movement of the door after closing movement of the door has covered the door opening until the door has reached fully closed position; and said control mechanism including cam and latch lever reset means operable upon fully closing the door to permit subsequent opening movement of the door.

DESCRIPTION OF THE PREFERRED EMBODIMENT The improved rotary depository is indicated generally at 1. It may be installed in a wall 2 of a bank or other building. A general or protective cover housing 3 is permanently mounted in the wall opening 4. The cover housing 3 has a top wall 5, side walls 6, a bottom wall 7, an angular back wall 8 and a front trim flange 9. A channel-shaped support slide tray 10 is provided on which the depository mechanism is mounted for insertion into the protective cover housing 3. When the mechanism is inserted from the rear of the wall 2 to the position shown in FIG. 2, the web 11 of channel 10 may be bolted to the bottom wall 7 of housing 3 by bolts not shown. Slide tray 10 has upstanding flanges 12 at each side thereof which engage and may be secured to the side walls 6 of housing 3.

A flange-like sleeve wall 13 extends downward (FIG. 2) from openings formed in the rear portions of hous ing bottom wall 7 and slide tray web 11 and sleeve wall 13 is telescoped into a sleeve 14 to form a connection with the chute 15 leading to a vault, chest or other safereceptacle (not shown) within the bank building. A spring actuated bolt 16 is mounted on bottom wall 7 of housing 3 and is adapted to engage a bolt plate 17 to hold the slide tray 10, and the depository assembly supported thereon, in installed position. Bolt 16 may be released by pull cable 18 which is only accessible from within chute 15 and in the vault or chest below to release the depository unit for removal from the wall.

A pair of saddle-like adjusting plates 19 have outturned bottom flanges or feet 20 mounted on the web wall 11 of slide tray 10. The adjusting plates 19 each have slotted openings 21 through which bolts 22 are engaged which adjustably mount and support the end or side walls 23 of the rotor housing. A top arcuate rotor housing wall 24 connects the rotor housing end walls 23. Similarly a bottom arcuate housing wall 25 also connects the rotor housing end walls 23. The outer edges 24a and 25a of housing walls 24 and 25 are spaced apart as shown in FIGS. 2 and 18 to define an access opening 251 for the rotor housing. The rear edges 24b and 25b of the housing walls 24 and 25 also are spaced apart as shown in FIG. 2 generally to define a discharge opening 252 for the rotor housing. A hood-like enclosure 26 (FIG. 2) closes the discharge opening 252 and is mounted on the rear top and rear end edges of and extends between adjusting plates 19 downward to the chute l5 and within the back wall 8 of cover housing 3.

DOOR AND DOOR FRAME ASSEMBLY The rotor housing is provided with a door and door frame assembly generally indicated at 27 and shown particularly in FIGS. 10,11,12 and 13. The door frame includes a bottom frame plate 28, a top frame plate 29, and support bars 30 to which the frame plates 28 and 29 are bolted at 31. A mounting block 32 is bolted at 33 to the lower ends of the support bars 30 at the ldower corners of bottom frame plate 28. A mounting bar 34 is connected to the upper ends of support bars 30 spaced from the top frame plate 29. The ends 35 of mounting bar 34 project laterally outside of support bars 30. Slide shafts 36 are mounted at their upper ends to the ends 35 of mounting bar 34, and at their lower ends to mounting blocks 32. Thus slide shafts 36 are spaced laterally outwardly of support bars 30 and extend parallel with support bars 30 on the door frame assembly 27.

The depository door 37 has a guide block 38 mounted at each of its corners. The guide blocks 38 are slidably journaled on slide shafts 36 for movement thereon between the lower or closed door position shown, for example, in FIGS. 2 and 10, and the fully open position shown in FIG. 18. The bottom door frame plate 28 is formed with a series of grooves 39 and the top frame plate 29 has a series of recesses 40 aligned with grooves 39. A series of projections 41 extending from plate 41a is mounted on the bottom face of the door 37 at the lower door edge 42, and these projections 41 move along grooves 39 and into recesses 40 as the door 37 is moved from its closed position of FIG. upward to its limit of opening movement as shown in FIG. 18.

A block 43 is mounted on the door frame assembly 27 extending between the bottom and top frame plates 28 and 29. The inner edge of block 43, the lower edge of top frame plate 29, the inner edge of right-hand support bar 30 and the upper edge of bottom frame plate 28 define an access opening for the door frame generally indicated at 44, large enough for a filled deposit bag to be passed through the opening 44 when the opening is uncovered by the door 37 upon moving door 37 upward to its limit of opening movement, when the lower edge 42 of the door is aligned with the lower edge of top frame plate 29, that is, the upper edge of access opening 44.

The outer surface of door 37 may be covered with a thin channel-shaped door finish member 45, having outer edge flanges 46 extending outward for a purpose to be described. The door 37 may be provided with an operating handle 47 as shown in FIG. 13.

The door and door frame assembly 27 is mounted on the rotor housing by bolting the support bars 30 at either side of the access opening 44 to chord-like sur faces 48 at the edges of rotor housing end walls 23 by bolts 49 (FIG. 13). When thus assembled, the access opening 44 formed by the door frame is aligned with the larger opening 25-] in the rotor housing formed between the top and bottom rotor housing wall edges 24a and 25a. A reinforcing bar 50 extends along the edge 24a ofthe top rotor housing wall 24 (FIG. 2), which engages the underside of top frame plate 29.

The rotor housing, and the door and door frame as 'sembly 27 when in place within protective cover housing 3 also include a trim frame 51 having a rearwardly projecting outer flange 52 which seats against the building wall 2. Frame 51 has inner rearwardly extending side flanges 53, an upper flange 54, and a lower flange 55. Flanges 54 and 55 terminate in vertical flanges 56 and 57, respectively, reinforced by top and bottom plate members 58 and 59. Plate 59 closes the space between trim frame flange 57 and the lower end of door frame 27. Plate 58 completes the closure of the trim frame 51 with the door and door frame assembly 27. The bottom edge 60 of plate 58 terminates just above the upper edge 61 of the door 37 (FIGS. 2 and 3).

A storage compartment for deposit slips, cards or the like may be provided at 62 in the corner zone below the upper trim frame flange 54. A door 63 closes compartment 62. A light fixture 64 with a light cover 65 extends across the top end of the trim frame 51 beneath the compartment 62 (FIG. 2).

KEY LOCK MECHANISM A key lock unit 65 is mounted on bottom closure plate 59 (FIGS. 1 and 2) which may be unlocked by keys furnished to bank customers using the depository and wishing to deposit bags of valuables in the depository. Key lock 65 has a rotatable barrel with a lever 66 projecting laterally behind plate 59. Lever 66 is pivotally connected at 67 with the lower end 68 of angled lever 69 pivotally mounted at 70 intermediate its ends on the underside of a front housing frame plate 71 which overlaps the left-hand edge of door 37 (FIGS. 1, l3 and 14).

The underside of the inner edge of plate 71 has a groove 72 (FIG. 13) into which one of the finish plate end flanges 46 on door 37 projects to prevent fishing into the housing between the door 37 and housing frame plate 71. A similar front housing plate 73 extends along the right-hand edge of door 37 (FIGS. 1 and 13), and plate 73 likewise has a vertical groove 72 in its inner surface into which right-hand door edge flange 46 projects to protect against fishing access to the depository 1.

The upper end of lever 69 is pivotally connected at 74 with a bolt 75 slidably mounted at 76 near the upper end of the underside of plate 71. The outer end 77 of bolt 75, when lock 65 is in locked. position, projects to a location engageable with upper and lower door notches 78 and 79 as shown in FIGS. 15 and 17. When key lock 65 is locked, the bolt 75 prevents slidable movement of door 37 beyond the position shown in FIGS. 17 and 19 by blocking engagement of bolt 75 with notch 79. When door movement is so blocked during movement of door 37 in the direction of arrow 80 in FIG. 19, the lower door edge 42 is located slightly above the upper edge of bottom frame plate 28, thereby forming a very narrow slot-like envelope opening indicated at 81 in FIG. 19.

Unlocking of key lock 65 by key 82 (FIG. 16), ro tates barrel lever 66 to the position shown in FIG. 16, actuating angled lever 69 to withdraw bolt 75 to a position which does not block door movement. This permits the door 37 to be moved upward to fully opened position shown in FIGS. 16 and 18 when the lower edge 42 of the door 37 is spaced a considerable distance away from the upper edge of bottom frame plate 28. This provides a bag opening, indicated generally at 83 in FIG. 18. When the door is in fully open position and until it is moved back to the position shown in FIG. 17, bolt 75 may not be moved to locking position, and key 82 may not be removed from key lock 65, because of interference by bolt 75 with the lower left-hand corner 84 of the door 37 (FIG. 16).

THE DEPOSITORY ROTOR The rotor construction is generally indicated at 85 in FIGS. 2, 4 and 13. The rotor 85 includes a main rotor shaft 86 preferably square in cross section. The ends of the shaft 86 are pinned by pins 87 to hubs 88 (FIG. 4) journaled in bearings 89 mounted in the rotor housing end walls 23. A series of sector plates 90 is mounted at spaced intervals along squared shaft 86. Each sector plate 90 is Z-shaped (FIG. 2), in cross section and has an arcuate finger 91 extending counterclockwise within the rotor housing (viewing FIG. 2) from the ends of the diametral portion 92. A groove 93 is formed in the outer cylindrical surface of each arcuate finger 91 of each sector 90. Ribs 94 and 95 formed on the inner surfaces of rotor housing walls 24 and 25, respectively, extend into grooves 93 as the rotor 85 turns clockwise in operation. Shear plates 96 are fixed to housing wall 25 (FIG. 2) in the spaces between adjacent sectors 91). Each shear plate 96 has a straight leg 97 and a sawtoothed leg 98 connected to the housing wall 25. The apex of each shear plate 96 is formed with an opening 99 through which the squared rotor shaft 86 extends, and within which shaft 86 may rotate.

The series of sectors 90 strung along shaft 86 thus form two rotor compartments indicated generally at 100, spaced 180 apart (FIG. 2). The top compartment 100 (FIG. 2) communicates with housing envelope opening 81, or bag opening 83, in a position to receive a deposit when the door 37 is open to form either opening 81 or 83. The lower rotor compartment 100 communicates with the sleeves 13 and 14 and chute through the discharge opening 25-2.

In operation, rotor 85 always rotates in a clockwise direction (viewing FIG. 2) as indicated by the arrow 101. Thus, any bag or envelope deposited in either of the two compartments 100 will be dumped into chute 15 upon rotation of the rotor through 180 and access to one of thevtwo compartments is provided when the door 37 is open. Upon 180 rotation of the rotor, the position of the two compartments 100 is reversed. Meanwhile, any object, whether bulky or string-like in nature will be sheared by the straight legs 97 of the shear plates 96. or will be caught by the saw-toothed legs 98 of the shear plates 96, as the diametral portions 92 of sectors 90 rotate past the shear plate legs 97 and 98.

The interfitting engagement between the sector grooves 93 and the housing ribs 94 and 95 prevents papers or unauthorized access fishing equipment, etc., from being inserted laterally or around in the clearance space between the sectors 90 and the housing walls.

Similarly, the projections 41 on the underside of the door 37 riding in the door frame grooves 39 will clear or wipe away any papers or objects left on the bottom frame plate 28 when the door is open.

A ratchet wheel 102 is fixed on one end of rotor shaft 86, the right end shown in FIG. 6. Wheel 102 has ratchet teeth which are engaged by spring pressed pawls 103 to control rotation of the rotor 85 in one direction only. The wheel 102 and pawls 103 prevent counterclockwise rotation of the rotor, viewing FIG. 6.

DOOR LATCH AND COUNTERWEIGHT BRACKET STRUCTURES A vertically extending strip-like bracket 104 is bolted at 105 (FIG. 3) to the left-hand housing end wall 23. An adjusting bracket 106 also is bolted by the bolts 105 to housing wall 23 and extends rearwardly ofthe mechanism. Bracket 106 has an adjustable screw 107 engaging a flange 108 at the top of left-hand adjusting plate 19. A strut arm 109 is mounted at 110 on the upper end of bracket 104 projecting upwardly forwardly and is connected at 111 with the left-hand projecting end 35 of door frame mounting bar 34.

A similar vertically extending strip-bracket 112 (FIG. 6) is bolted at 113 to the right-hand housing wall 23. An adjusting bracket 114 similar to bracket 106 also is bolted by bolts 113 to housing wall 23 and extends rearwardly of the mechanism (to the right in FIG. 6). Bracket 114 has an adjustable screw 115 engaging a flange 116 at the top of right-hand adjusting plate 19. A strut arm 117 similar to strut arm 109 is mounted at 118 on the upper end of bracket 112 projecting upwardly forwardly, and is connected at 119 with the right-hand projecting end 35 of door frame mounting bar 34.

Strip brackets 104 and 112 and strut arms 109 and 117 support the upper end of the door frame assembly 27 so as to minimize springing of the door frame and provide ease of sliding movement of the door 37 on slide rods 36.

The adjusting screws 107 and 115 engaging the flanges 108 and 116 on adjusting plates 19, as well as the slotted bolt connections 2122 between the adjusting plates 19 and the housing end walls 23, permit the rotor housing to be adjusted to a proper level position with respect to remaining parts of the depository.

Pulleys 120 and 121 are journaled adjacent the ends of strip bracket 104, and a third pulley 122 is mounted at 123 on the left-hand housing end wall 23 (FIG. 3). An upper cable 124 is connected at one end to pin 125 mounted on a bracket 126 (FIG. 3) carried by the upper left-hand door guide block 38 (FIGS. 10, 11 and 12). Cable 124 is looped around pulley 121 and is connected at its other end to a door counterweight 127. A lower cable 128 is looped around pulleys 120 and 122 and is connected at one end to pin 125 and at its other end to counterweight 127. Counterweight 127 moves within a protective cylinder 129 (FIG. 3) mounted by strap 130 on strip bracket 104.

Cables 124 and 128 and counterweight 127 form an endless loop connected at 125 to door 37, so as to counter-balance the weight of door 37 in all positions of the door, so that little effort or force is needed to move the door 37 from one position to another in either direction of linear movement in the door frame assembly 27.

DOOR LATCH MECHANISM A door latch ratchet bar 131 extending parallel with the slide shafts 36 is mounted by bolts 132 and spacers 133 (FIGS. 6 and 9) on the right-hand housing end wall 23. A latch cam 134 having an inturned finger 135 is adjustably mounted by slot and bolt connections 136 on the outer end of ratchet bar 131 and at an intermediate point on bracket 112 (FIG. 6).

The upper right-hand corner door guide block 38 has a pawl 137 mounted on its outer face in a position to engage, under controlled conditions, the ratchet teeth of ratchet bar 131. Pawl 137 is pivoted at 138 intermediate the ends of pawl 137 on block 38. A release cam 139 also is pivotally mounted at 140 on the door guide block 38. Release cam 139 normally is in the position shown in FIG. 6 holding pawl 137 in the position illustratcd. Pawl 137 is spring biased to engage the stub end of cam 139, as shown. In this position of the pawl 137, and cam 139 permits the pawl to clear the teeth of ratchet bar 131 when the door is moved upward in the direction of the arrow 141, shown in FIGS. 6 and 7.

During upward movement of the door in the direction of the arrow 141, as the pawl 137 and cam 139 reach the position shown in FIG. 7 (at which time the envelope opening 81 has been formed below the lower edge 42 of door 37), the pointed end of release cam 139 is engaged by the latch cam finger 135 on latch cam 134. Finger 135 trips release cam 139 which moves to the position shown in FIG. 7. As the door 37 continues to move upward to the limit of its opening movement, shown in dot-dash lines in FIG. 7, pawl 137 and cam 139 will assume the positions shown. In this position the pointed end 142 of pawl 137 is adapted to ratchet along and engage the teeth of ratchet bar 131 when the door moves downward toward closed position as indicated by the arrow 143 in FIG. 8.

The pawl 137 was reset to operative position, as shown in FIG. 7, just after the envelope opening 81 is formed on opening movement of door 37 in the direction of the arrow 141, at which time pawl 137 clears the upper end of ratchet bar 131. The pawl and ratchet 137-131 become effective during downward movement of the door in the direction of the arrow 143, just as the door has closed the envelope opening 81, to pre' vent reverse or opening movement of the door, as shown in FIG. 8.

Thus, the door latch mechanism, best illustrated in FIGS. 6, 7, 8 and 9, prevents opening movement of the door after the door has moved to a location just closing the envelope opening 81. The latch mechanism is reset, when the door is fully closed, to permit subsequent opening movement of the door.

This resetting of the latch mechanism occurs, as shown in FIG. 6, when the pointed end 142 of pawl 137 is engaged by the raised end 144 at the lower end of ratchet bar 131. This engagement of the pawl 137 v moves the pawl to the position shown in FIG. 6, whereupon the release cam 139 drops by gravity to the position shown, holding the pawl in release position.

RACK AND PINION DRIVE A rack bar 145 is pivotally connected at 146 at its upper end to the bracket 126 on the door guide block 38. The rack 145 preferably has s shock absorbing connection between its rack portion and the mounting por tion 147 containing the pivot connection 146. The mounting portion 147 includes a pin and slot connection 148 between rack 145 and mounting portion 147, spring biased at 149 to project the rack portion 145 away from pivot 146. This shock absorbing connection absorbs the shock which may occur when a user pulls down too forcefully on the door handle 47 to close the door 37.

Anoffset bracket 150 (FIGS. 3 and 4) is mounted on the left-hand housing end wall 23 on which a stub pivot shaft 151 is mounted. An L-leg 152 of bracket 150 is pivotally connected at 153 to an end 154 of rotor shaft 86 (FIG. 4). A pinion 155 is journaled on the rotor shaft end 154 and meshes with a similar pinion 156 journaled on stub shaft 151. Pinion 156 engages rack and is held in driving engagement by rack retainer 157 which also is journaled at 15 8 on stub shaft 151.

Pinion is formed as a fixed assembly with a V-cam member 159 and a clutch segment 160. The assembly 155459-160 (FIG. 4) is journaled on the rotor shaft end 154, and is axially movable thereon, being biased by spring 161 normally toward the full line position shown in FIG. 4 when the cllutch is engaged, but movable to the dot-dash position shown for clutch disengagement.

Similarly the hub 88 has a clutch blade 162 fixed thereto and rotatable therewith and with rotor shaft 86.

The clutch blade 162 has diametrically opposite similarly formed contoured ends 163, each formed with an engaging notch 164. The ends of clutch blade 162 have an enlarged reinforcing pad 165 formation (FIG. 22) to provide an enlarged engaging surface 166 at the notch 164.

A lever stop 167 is pivotally mounted at 168 on the lefthand housing end wall 23 and has a spring pressed rubber engaging pad 169 at its outer end adapted to be engaged by the engaging surface 166 of clutch blade 162 to hold the clutch blade 162 against counterclockwise rotation (FIG. 3).

The hub 88, on which the clutch blade 162 is fixed, also has a clutch segment 170 formed thereon for clutching engagement and release: with the clutch segment 160 on pinion 155.

Lever stop 167 has a V-shaped pivoting link 171 pivotally mounted at 172 thereon which normally hangs in the position shown in FIG. 3. Further clockwise movement of link 171 is prevented by stop pin 173. V-carn 159 has a nose 174 which, upon rotation of the V-cam in either direction, engages one side or the other of pivot link 171. Cam nose 174 either passes the link (FIG. 20), or engages the link 171 and raises lever stop 167 to the position of FIG. 23. This releases engage ment of clutch blade 162 with rubber pad stop 169.

OPERATION OF DRIVE MECHANISM A bank customer wishing to make a deposit normally will approach the depository as illustrated in FIG. 28 with the door 37 closed. The customer grasps handle 47 and moves the door 37 to the position shown in FIG. 29, if the deposit is in the form of an envelope 175. Movement of the door 37 without unlocking the key lock 65 is limited by the outer end 77 of bolt 75, so that the door 37 can only expose the envelope opening 81 to permit the customer to insert the envelope 175 through the opening 81. Then the envelope drops into the upper rotor compartment 100 (FIG. 2). This intermediate position of the door 37 and the envelope opening 81 formed, also is shown in FIG. 19.

A number of events occur during the opening movement of the door from the closed position of FIG. 3 to the intermediate envelope opening position of FIG. 19. As the door raises in the direction of the arrow 80 (FIG. 19), a rack 145 rotates pinion 156 counterclockwise as shown by the arrow, and pinion 156 rotates pinion 155 clockwise. The V-cam 159 is fixed to pinin 155 and rotates therewith. The position of the V-cam 159 is shown in FIG. 20 just before the door 37 has exposed the envelope opening 81. At this time the nose 174 of the V-cam engages pivoting link 171 and rotates link 171 counterclockwise, as shown in FIG. 20. V-cam 159 then continues to rotate in a clockwise direction to the full line position shown in FIG. 19 when the envelope opening 81 is exposed and further opening door movement is stopped by the end 77 of bolt 75. Meanwhile link I71 drops by gravity back to the position shown in FIG. 19.

The dot-dash position of V-cam 159 in FIG. 19 illustrates how the V-cam initially engages link 171. Meanwhile the upper high cam surface 176 (FIGS. 4 and 5) of clutch segment 170 on drive shaft 86 has been engaged by the high cam surface of hub cam on clutch segment 160 on pinion 155. As pinion 155 rotates it is moved axially by interengaging cam surfaces to the po sition shown in dot-dash lines in FIG. 4, to permit the cam tooth on clutch segment 160 to ratchet over the cam tooth on clutch segment 170, as shown generally in FIGS. 26 and 27.

After the deposit of envelope 175 has been made, the customer moves handle 47 and door 37 downward from the position of FIG. 29 to that of FIG. 28. This also is illustrated by the arrows in FIGS. 23 and 24. FIG. 23 shows the position of the door 37 just after the envelope opening 81 has been closed. Rack 145 moves downward rotating pinion 156 clockwise and pinion 155 counterclockwise. V-cam 159 similarly moves counterclockwise with pinion 155, and the nose 174 of V-cam 159 engages link 17]., raising the link 171 and lever stop 167 to the position shown in FIG. 23. When the lever stop 167 is raised, its rubber pad stop 169 is moved above the outer end of the upper section of clutch blade 162 which permits clutch blade 162 to rotate counterclockwise thereby permitting the engaged clutch cam surfaces of segments 160 and 170 (FIG. 26) to rotate the drive shaft 86 counterclockwise through 180.

The rotor thus is rotated within the rotor housing, counterclockwise (viewing FIG. 24), to transfer the top rotor compartment 100 of FIG. 2 to the bottom position. FIG. 24 shows the position of the rotor and drive elements just before the door 357v has been completely closed by the engaged clutch. The clutch blade end 177 directed downward in FIG. 23, at this time is in the upper position of FIG. 24 so that its engaging surface 166 will strike and be stopped by the rubber stop pad 169 mounted on lever stop 167, as shown in FIG. 3 which shows the door 37 completely closed.

The end wall 23 of the rotor housing is broken away in FIG. 24 to show portions of the rotor segments, etc. Thus the drive mechanism is only activated to rotate the rotor shaft 86 to move a rotor compartment containing a deposit from the receiving to the chute discharging position during that portion of the door closing movement which occurs after the door has just closed the envelope opening 81. Furthermore, such movement imparts 180 movement to the rotor which requires less effort than 360 rotor movement which frequently is utilized in prior rotary depositories.

Moreover, as described above, the door 37 is latched against opening movement after initiating closing movement to a location just closing envelope opening 81. In this manner, since rotor movement is initiated at the same time, the door 37 cannot be opened once movement ofthe rotor has commenced. Since the rotor can only rotate in one direction, rotor movement must continue on for the 180 cycle of door operation and until the door has been completely closed. At this time,

the door latch is reset to again permit opening movement ofthe door. At the same time, the rack and pinion and clutch drive again is operative to initiate rotor movement only upon closing movement of the door and during a cycle of door opening and closing movement, after the opening for an envelope or bag has been completely closed.

If the bank customer has a bag to deposit, requiring a larger opening in the depository, the customer must first unlock key lock 65 with a key 82 as shown in FIG. 30. The door handle 47 then is grasped and the door 37 may be raised to the limit of opening movement as shown in FIGS. 18 and 30, to provide the larger bag opening 83, whereupon a bag 178 may be deposited within the upper rotor compartment 100.

The drive mechanism in fully opening door 37 operates in the same manner for bag deposit, as described for exposing an envelope opening 81, during the initial door opening movement to the position shown in FIGS. 19 and 29. Thereafter, as door 37 continues to move upward to full open position, as shown in FIG. 18, pinion continues to rotate in a clockwise direction and V-cam 159 moves to the position shown in FIG. 18 beyond that shown in FIG. 19. Meanwhile the clutch continues to remain disengaged and will not become engaged again until closing movement of the door positions the door at a location just completely closing the letter opening 81. Thereafter the clutch engagement and rotor movement continues, as described in connection with the operation of closing the door from the intermediate envelope opening position.

If desired, a light 179 may be mounted on one of the rotor housing end walls 23 as shown in FIG. 19 for lighting the interior of the rotor housing. Also the rubber pad stop 169 on the lever stop 167 may be mounted on a plate 180 spring pressed at 181 to absorb the shock of stopping rotation of the rotor.

The new depository construction is characterized by extreme convenience and simplicity of construction and operation. The rotor and its drive and control mechanisms and elements are of elementary and simple mechanical design and construction. The door is completely counterbalanced so that little effort is required to move it in either direction. Thus, the work to be performed by a customer in manually actuating and driving rotor movement is a minimum and the operation accordingly is substantially effortless.

The depository accommodates both envelopes and bags while avoiding the requirement of power operation, although rotor movement may be motorized if desired. The various aspects of the concept are achieved by providing a rotor having two similar rotor compartments spaced 180 apart, so that the rotor is only required to be moved 180 for each deposit operation. Operation of the rotor is in one direction only and is controlled by door movement which also is in one direction, linearly, for opening to expose either an envelope or a bag opening.

Accordingly, the improved construction is simplified, provides an effective, safe, minimum cost and efficient device, accepting either envelope or bag deposits, may be readily operated manually by a customer, and provides a depository construction achieving all of the enumerated objectives, eliminating difficulties encountered with prior devices, and solving problems and obtaining the new results described.

In the foregoing description, certain terms have been used for brevity, clearness and understanding; but no unnecessary limitations are to be implied therefrom beyond the requirements of the prior art, because such terms are used for descriptive purposes and are intended to be broadly construed.

Moreover, the description and illustration of the invention is by way of example and the scope of the in vention is not limited to the exact details of construction shown or described.
